Question

A car covers a distance of 40 km in first hour and 50 km in the second hour. What kind of motion is this? ​

Answer 1

This is non-uniform type of motion.

Explanation:

A car covers a distance of  first hour = 40 $\dfrac{km}{hr}$,

A car covers a distance of second hour = 50 $\dfrac{km}{hr}$

∴ Averrage Speed = $\dfrac{2AB}{A + B}$

= $\dfrac{2(40)(50)}{40 + 50}$

= $\dfrac{80(5)}{9}$

= 44.44 $\dfrac{km}{hr}$

Hence, this is non-uniform type of motion.

Answer 2

Explanation:

non uniform type motion
